mines, quarries, mills and other production plants in mountainous locations. I

It is the main object of the present invention to provide a simple mechanical structure which combines separated ways for the conveyance of materials to and from an elevated location, with a common element to effect and assist the movements of the same.

Further objects of the invention will appear in the course of the following description made with reference to the accompanying drawings which illustrate an apparatus embodying my invention in the best and simplest form at present known to me.

In the drawings in the several views of which like parts are similarly designated,

Figure 1 represents a partially sectional side elevation of the transportation system in its operative position;

Fig. 2, a perspective view of one of the sections of which it is composed, and

Fig. 3, a perspective view of the lower end portion of the system.

Referring to the drawings by numerical reference characters, 2 designates a chute preferably made up of a plurality of end-to end adjoining sections mounted in transversely disposed frames 3 which are formed to provide cross ties or sleepers 4 and 5 respectively above and below the chute.

Parallel rails 6 fastened on the upper cross ties are provided to support and guide the cars 7 of a cable-railway hereinafter to be described.

The spaces above the chute between the cross-ties are preferably covered by a flooring 8 to exclude dust and dirt and said flooring may be provided with sliding doors, as shown at 9 in Fig. 2, to afford access to the contents of the chute if so desired.

The cable railway hereinbefore referred to comprises an endless cable or chain 10 which is supported on sheaves or drums l2 and 13 at opposite ends of the chute.

The upper stretch of the cable passes over the floor of the chute intermediate of the rails and is' supportedat regular intervals upon idle wheels 14 and the lower stretch of the cable passes throu 'hthe chute in proxim- 1ty to the bottom sur ace thereof.

The endless carrier member is operated by a motor 15 which has a driving connection wlth the sheave at one end of the chute.

In the operative condition of the system the chute is placed in an inclined position to connect a mine, quarry or mill with a point of lower elevation.

The motor for the operation of the cable is mounted on a stationary foundation l6 and preferably within an inclosure 17 adjacent the lower end of the chute, and the rails at the upper end of the same may be extended as shown at 18 in Fig. 1 to connect with a road or level surface leading to the plant.

The chute is open at its upper end to rece ve the material tobe conveyed from. the mine or quarry and it has at its opposite end one or more lateral outlets 19 for the discharge of the same.

In the operation of my invention the railway on top of the chute is utilized to transport building materials, machine parts and other supplies to the elevated plant, it being understood that the cars in-which the materials are carried, are provided with the usual grips for their connection with the upwardly moving cable.

The product of the mine, quarry or mill is dumped into the upper end of the chute and aided by the downwardly moving flower stretch of the cable, is conveyed to the discharge openings at the lower end of the same.

It will thus be seen that my invention provides in one structure, upper and lower ways for the simultaneous conveyance in opposite directions of different materials and that in combination with said structure a single carrying and impellent element is employed to effect the movement of the material along said ways.

Having thus described my invention what I claim and desire to secure by Letters-Patent is:

1. In a transportation system, the combination of a conveying trough, a railway supported thereon, and an endless cable adapted for the connection of cars moving on the railway, and passing throughthe trough for engagement with material therein.

2. In a transportation system, the combination of an inclined conveying trough, a railway supported thereon, and an endless cable adapted for the connection of cars moving on the railway, and passing downframes having cross ties above and below the same, and a railway supported on the upper ties.

4. In a transportation system, the combination of a conveying trough, including in its construction superposed means for thesupport of a railway, and a railway on said means.

5. In atransportation system, the combi- 15 nation. of .an interiorly concave conveying trough, a railway supported thereon, and an endless cable adapted for the connection of cars moving on. the railway, and passing throughthe lower portion of the trough for 20 engagement with material therein.

In testimony whereof I have aflixed my signature. 7 I OYRIL C. COX.
